Pros: Easy handling, great sharpness, high quality
Cons: Not much
Sharpness: 9    Aberrations: 10    Bokeh: 9    Handling: 10    Value: 10    Camera Used: K10D & KS2   

Very easy handling for an MF lens, high quality overall feel, very sharp - even sharp wide open, although it does get sharper stopped down one step. Very good value of a lens and one I would recommend to anyone looking for something like this.

Pros: really very sharp standard zoom lens, stopped down at f 8
Cons: 35 mm few CA in the corners
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 9    Value: 10    Camera Used: k-x k200 sf-x k-2, mgf, mv, mz 5, Z-20 p, z.70   

my item is quite different.

I've got still an other Osawa mark II (4-5/70-210)and was really convinced by quality. This lens is constructed especially for close ups, plants flowers, portraits. Far distant object are quite sharp;but near it seems a few sharper. I am using it regulary at 105 mm as macro lens with macro ring. A pure macro tele lens is much more expensive.

because oh its low price and no visible CA's in tele position and very high sharpness of my item 9.5 points

+++ extreme high sharpness at 105mm with f 8-11, if close ups are shooted

+++ no visible CA's in tele mode very well corrected

++ very good sharpness at 50 mm

+ good sharpness at 35 mm, corners a few weak and small CA's visible in the edges

++ excellent color rendition and

++ contrast is very fine, too

highly recommended

Pros: Cheap
Cons: Soft till f8, not for "quick" purposes
Sharpness: 6    Handling: 6    Value: 7   

I did what is known as the Newspaper Test: basically paste a newspaper page to a wall, sit the camera perfectly horizontal & have the newspaper fill the frame, shoot & see sharpness at different FLs & apertures

Aberrations & Bokeh:
I cannot comment as I haven't tested that
(dunno how to, really)

Sharpness:
Wide-open (f3.5) it is soft over the whole frame, stopping down to f5.6 & f8 it becomes significantly sharper
My copy is softer on the left side and the bottom right corner at f5.6 & 8, but center & right is decently sharp
That is on all focal lengths

The Macro focus gives a very nice shallow DOF as well, that's one of the reasons I like that lens

Handling & Ergonomics:
This lens has a slide-zoom; meaning you slide the moving part away to zoom in & vice versa
It has a long focus throw, almost half a turn from minimum focus point to infinity
The "Macro Focus" ring is between the aperture & focus rings, with a button that is facing upwards (12 o'clock) that you press in order to turn and focus closer than the 1.5 meter normal focusing (up to ~3 inches from the front element at 35mm)

as far as i can tell, this lens was designed to be held with fingers facing upwards & thumb below it
not the usual grasp that is as if you're carrying the camera in your palm
I found that the easiest type of grip that allows you to focus, zoom & access macro zoom almost simultaneously

It takes quite the long time for me to focus with this lens (and that with focus peaking!) so I wouldn't recommend it for situations that require speed (street candids, photojournalism...etc)


Overall:
I maybe a bit biased due to my obsession with "vintage lenses" but it is what it is, an extremely cheap lens (most Osawa lenses are, actually) that is not-so-special performance wise
Haven't tested for flare but I do expect it to be very prone to flare.
Personally, the soft focus wide open & flare are elements I like to have, but as most I consider them a disadvantage in absolute terms
